Data of air temperature. humidity. wind speed, crop yield and forest cover percentage were investigated and collected in some of counties of Heilongjiang Province, where windbreak systems were established in the last thirty years. Through analysis, an evaluation index system estimating regional ecological benetits of windbreak systems was set up, which consists of both a vegetation index system and a climate index systeln. The former includes a forest cover percentage index and a crop yield index; the later does three variable indexes of wind speed, air temperature and humidity. An integrated regional ecological benefit index.was developed through combinations of some coined evaluation indexes from the evaluation system.And to take Zhaozhou County and Anda County as a case study, the regional ecological benetits since establishment of windbreak systems of the two counties were evaluated dynamically using the integrated index.展开更多

It is not the primary objective of this paper to discuss the benefits and effects of trade or WTO membership as such. Rather, the focus is on how the growth of a country (either China or any other country) may increase the benefits of its trading partners. In particular, which countries/regions will benefit more from the growth of China? And from the growth of which countries/regions will China benefit more?Greater openness increases efficiency and productiv-展开更多
